Lifecycle Profiles

The document explains the two types of Lifecycle Profiles in LEAP: Aging Profiles, which track how variables like fuel economy change as devices age relative to a new device, and Distribution Profiles, which describe vintage distributions within a stock. It details the software interface for creating, editing, and importing these profiles, including the option to define values via manual data points or an exponential curve formula.

• Lifecycle Profiles are categorized into Aging Profiles and Distribution Profiles. Aging Profiles track how a variable changes as devices age, expressed as a percentage relative to a new device (starting at 100%), while Distribution Profiles describe the distribution of vintages within a stock of devices used in Current Accounts.
• Users can manage profiles through a two-pane interface that allows for the creation, renaming, and deletion of profiles, as well as the ability to import or export data using Excel spreadsheets.
• Profile values can be entered manually as data points or generated using an exponential curve based on the formula V[t] = V[t-1] x Exp(t * Constant).
